To all whom it may concern:

Be it known that I ALFRED C. MooRK, a citizen of the United tates ofAmerica, and a resident of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Im rovements inGas-Burners, of which the follbwing is a specification.

The purpose of this invention is to provide for eflicient combustion byeffecting an extremely intimate mixtureof the incoming gas and air by asubstantially two-part burner formed of a pair of simple castin s.

The objects of the invention are accomplished by the device shown in theaccompanying drawings, in which- Figure 1 is a transverse verticalsection of a gas burner constructed according to this invention.

Fig. 2 is a bottom plan view of the cover portion of the burner.

Fig. 3 is a plan view of the base of the burner. 1

The invention as embodied in the drawings comprises a base portion andan interfitting hollow cover, said cover having a depending serratedconical spreader opposite the central air and fuel inlet in the base.Both the cover and the base are provided with overlapping inwardlyprojecting flanges which are toothed or serrated, the serrations beingin staggered relation, and also being staggered with respect to theserrations on the conical spreader. By this ar ran ement the incominggas and air is first pro ected against the central spreader on the coverand divided into a plurality of streams which strike against the toothedportion of the flange on the base, thusbeing broken up and caused toeddy around through the interdentals in the flange and then, by strikingthe flange on the cover, being further broken up before passing throughthe openings in the latter flange and toward the" burner outlets in thecover.

Referring to the drawings, the base 1 is in threaded engagement with thesupportin nipple 2 having the usual air and gas in ets of the Bunsenburner. The cover portion 2 is a hollow cylindrical member the sidewalls 3 of which rest on the base 1 outside of a small annular centeringflange 4. Parts 1 and 2 of the burner are secured together by a pair ofbolts 5. The top 6 of the cover 2 has a central depending serratedconical spreader 7 opposite the outlet Application filedlugust 26,1920.'

are in staggered relation with upstanding teeth 9 of the annular flange10 surrounding the cone 7 and integral with the base 1.

Thecover 2 is provided with a depending,

annular flange 11 surrounding the flange 10' teeth 9 of flange 10. Thespace 13 between the flange 11 and the side wall 3 of the coverprovidesfor a further mixture of the gas and air as the currents eddy inthis space before leaving-the burner through the burner outlets 14.

In the operation of the device the air and gas entering it through thenipple 2 is first divided into a plurality of streams by encounteringthe conical spreader 7. This spreader serves to direct more or less thedivided streams against teeth 9 of the flange 10, the gas and air beingmixed upon re-.
